BWUHHHHH?!?! Why? Doesn't make sense. Maybe they'll pick up a Russell kid and make it worth someone's time. I mean, I love that they'll be here, but in Sonoma? While Watkins Glen, Laguna Seca, and Road America are without open wheelers?

It's because that's where the WTCC will be going and Auto GP wouldn't be much of a support package if they went elsewhere.

Edit: Ah, missed a post explaining the same thing. Sorry. Nothing to see here!
